Product overview
DK112 is a secondary feedback flyback AC-DC off-line switching power supply control chip. The chip adopts highly integrated CMOS circuit design, with output short circuit, secondary open circuit, over temperature, over voltage and other protection functions. The chip has built-in high-voltage power tube and self-powered line, with few peripheral components, simple transformer design (the transformer that isolates the output circuit only needs two windings) and other characteristics.
